After you have added products to the commercial catalog, you need to add this catalog to the Bitrix24 Online Store.

You can place the catalog of your products online when editing the online store. Open the Online Store features widget and click the gear button.

Then open the Catalog settings tab.

Select the Catalog folder.

Don't forget to save the changes. The products will be displayed on the Catalog page.

If you open the Products block settings, you will see ={$sectionId} in the Section ID field. Don't edit this value – it helps your clients find a product using search and filter.

After you place the commercial catalog on your online store, you can add links to the catalog sections to other blocks. For example, click on the menu item to add an action on click. Select the Open product page action in the block settings and specify the required section.
